Subject: can: kvaser_pciefd: Set CAN_STATE_STOPPED in kvaser_pciefd_stop()
From: Jimmy Assarsson <extja@xxxxxxxxxx>
commit aed0e6ca7dbb8fbea9bc69c9ac663d5533c8c5d8 upstream.
Set can.state to CAN_STATE_STOPPED in kvaser_pciefd_stop().
Without this fix, wrong CAN state was repported after the interface was
brought down.
